The invention provides a four-directional shuttle vehicle control system based on road right tokens. The four-directional shuttle vehicle control system comprises a WCS, a communication module, a shuttle vehicle locating module and a vehicle-mounted control module, wherein the communication module, the shuttle vehicle locating module and the vehicle-mounted control module are arranged on a four-directional shuttle vehicle. The communication module is connected with the WCS in a wireless mode, receives a shuttle vehicle task message and outputs the shuttle vehicle task message to the vehicle-mounted control module. The vehicle-mounted control module controls the shuttle vehicle to complete a series of actions according to the task message. The shuttle locating module determines the coordinate information of the position of the shuttle vehicle by reading address labels on a storage rack or the number of photoelectric signs on a pallet station and outputs the coordinate information to the vehicle-mounted control module. The vehicle-mounted control module feeds back the coordinate information of the four-directional shuttle vehicle, the state information of the shuttle vehicle and task schedule information to the WCS through the communication module. By the adoption of the four-directional shuttle vehicle control system based on the road right tokens, the carrying efficiency of the shuttle vehicle and the throughput rate of a storage system can be remarkably improved by optimizing a route plan, vehicle dispatch and traffic control.
